The SRCDAT (change date) field is one of three fields in each PF-SRC, the other
two being the SRCSEQ (sequence number) and SRCDTA (statement text).

Modifying the SRCDAT field when a line is updated is the responsibility of
whatever populates the file (such as an editor).

When using CPYF to a PF-SRC, the SRCOPT(*SEQNBR *DATE) renumbers statements and
sets all dates to zero.  This is in essence what happens with a FTP transfer of
a source member.  Only the SRCDTA field is transferred by the 400 FTP server,
unless you build a LF over a specific member and transfer using the logical
(yuck).

The IFS is more or less like just the SRCDTA portion of a PF-SRC.  If the source
date was stored with each line, the compilers would have to recognize it and
ignore it, and the editor maintain the date and store somewhere within the text
of the line.
